Microsoft has been working hard to get the word out on Office 365 and its latest efforts to drive adoption of its subscription-based productivity offering are in the United Kingdom. The company has teamed up with WiFi hotspot provider The Cloud to provide free access to commuters at numerous UK railway stations.

The Cloud already offers 15 minutes of free web access at many of the UK's larger stations, but for the next month, Microsoft's sponsorship deal will bring unlimited access to all users, with no restrictions on the number of devices that can be connected, the amount of data that can be downloaded or the duration of your connection.

Users connecting to the service will see a branded launch page when they go online, providing links to more information on the Office 365 offering, Windows 8 and the Surface RT tablet.

Microsoft UK's chief marketing officer, Philippa Snare, said the campaign "is designed to help commuters tap into new ways of working. The mobile workforce is constantly growing and, as such, so is the need to access mobile internet." She added that, "simply put, our aim in sponsoring unlimited free WiFi is to ensure users are able to work anywhere - in the office, at home and in between".

Microsoft and The Cloud will be offering the free unlimited WiFi access through to April 24, 2013. Access will be offered across the London Overground network, as well as at larger stations on the First Great Western and Greater Anglia networks.
